HiPERCAM/ULTRACAM observations of PSR J2051-0827

Optical observations of PSR J2051-0827 taken by the high-speed triple-beam CCD camera ULTRACAM on the William Herschel Telescope, and by the high-speed quintuple-beam CCD camera HiPERCAM on the Gran Telescopio Canarias. As presented in Dhillon et al. 2022 (MNRAS, in press, https://arxiv.org/abs/2208.09249). The letter after the underscore in each file name represents the observing filter for that specific file. For the ULTRACAM data, the columns are:<br> 1) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node),<br> 2) flux density (in erg cm^-2 s^-1 Hz^-1)<br> 3) flux density uncertainty (in erg cm^-2 s^-1 Hz^-1) For the HiPERCAM data, the columns are:<br> 1) MJD time<br> 2) orbital phase (in rotations, with phase = 0 corresponding to pulsar's ascending node),<br> 3) flux density (in erg cm^-2 s^-1 Hz^-1)<br> 4) flux density uncertainty (in erg cm^-2 s^-1 Hz^-1)
